Is this mix soil or soilless?

[philbu]

Hi,

I'm not new to growing, but new to this mix. I want to make sure i get the pH right, so should i consider this soil or soilless?

Medium is roughly Compost 30%, Promix 20%, Earthworm castings 20%, perlite 30%.

Thanks!

that'd be soil, in my head, anything that has a bunch of humus, and composted organic material is soil.
but why does that make a difference?
If it were me i'd add more aeration and peat to that mix.
or aeration and coco.
also depends on what type of compost you have.

I would say soil, since it has compost and worm castings.

Thanks for the responses. Yeah, I guess I'll go with "soil". Worm castings can be considered a biological component of soil. There are worms in soil, right? Compost is organic matter, full of organisms and even though it may be only 5% of soil makeup, we all know its benefits. I have plenty of both in this pro mix. : )
